To all 'whom t may concern:

Be it known that I, IOHN J. Hers, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, lhave invented an lm rovement in Automatic Boot and Shoe Levelmg Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates to machines for leveling or beating out the out soles of boots and shoes. Machines for this purpose as at present generally constructed are of two principal types, known respectively in the art as direct pressure7 and as Hautomatic or roll machines. The. direct pressure machines employ a jack to receive the shoe and opposed to the jack is an iron form, cast and finished to present the. desired contour for the sole bottom. This mold is .brought directly and under heavy pressure, upon the previously tempered shoe sole, and molds or Vpresses the s-ame into perfect conformity to the mold surface. The molding or leveling pressure insuch machines is, of course, uniformly and simultaneously distributed over the entire area of the sole to be leveled and is in other respects advantageous because there is no tendency to distort or twist the shoe. -Furthermore, Aany desired contour may be given to the sole by the use of a properly shaped mold.

With direct pressure machines the pressure must necessarily be great in order that when distributed over the large surface to be leveled every part of such surface shall receivea suflicient leveling press-ure, and therefore the use of such machines has been confined mostly toMcKay seWed shoes which are sewed with the Wooden last removed, thus leaving the shoe in readiness to receive a strong iron last such as is really necessary to withstand the heavy direct pressure of such machines.

Attempts have been made to use direct pressure machinesin the, leveling'of welt shoes where the `Wooden last remains, in the shoe ractically throughout the period of manu acture but Without success. It has been'fou'nd that the variationsin depth of Wooden lasts With variations in thickness of stock-used have produced such a variationin the leveling pressure that the lasts have frequently been crushed or the shoe damaged.

Particularly has this been true Where the pressure intended to be distributed over the entire sole to be leveled has, by reason of some inequality or unevenness, been brought to bear upon some one or. more comparatively small areas, for in such cases obviously an excess of pressure is received at such point and .damage has resulted. These objections have led to the very general use of what is known in the art as the automatic7 leveler, the principal characteristic of which is a leveling roll that is given a rapid and short vibrating movement lengthwise the shoe and is` at the same time caused to travel or progress slowly along the shoe 'sole between thc toe and the heel thereof, vibrating rapidly during its progress or travel so that every principal part of the sole is subjected to the action of this roll under apressure that is always sufficient to perform the Work at any one point, but liever sufficient to do damage should the depth of last be excessive or should the last be improperly positioned.

Roll machines have. usually been provided with a single roll only, and its vibratory and progressive movements have usually been in the direction of the length of the sole. But a roll, the concavity or curvature of Which is fitted to the cross-sectional curvature of the sole at one part thereof would not fit that at another portion nor at the more pronounced crown or curvature of tlie shank. In attempting to correct thisfault, the rolls vhave been canted first to one side and then to the other, split rollsV have been used 'and rolls made up of sections mounted upon flexible shafts intended to fit a sole bottom Whatever its curva-ture, but with unsatisfactory resu'lts. Moreover, the application of this pressure at a single constantly varying point in the length of the sole and first at one and then at the opposite side of the sole tends to buckle and twist the sole out of shape.

My invention among other things aims to provide a leveler of the automatic or .r'oll7 type that will more nearly approximate the accuracy of results obtained by direct pressure machines and that shall be open to few, if any, of the faults of the present prevailing types of roll machines.

My invention comprehends many other features and ideas, some of which are ap licable to the older type of machines, al of which together with the foregoing, will be more clearlyl understood and appreciated loo from a detailed description of a machine illustrating one embodiment of my invention. It is to be understood, however, that my invention is `y.not limited to the embodiment here selected 4for illustrative purposes.

In the drawings ,-Figure 1 in side elevation shows a machine illustrating one embodiment of my invention; Fig. 2 is a righthand end' or front elevation of the machine shown in Flg. 1; Fig. 3 is a top or plan view ofthe `machine shown in Figs. l and 2; Fig. L.tis an enlarged detail and diagrammatic view illustrating the movements of the `jack in presenting the leveled shoe for removal by the operator at the end of the leveling operation; Fig.

Fig. 12 is a detail view of the leveling device or roll showing more clearly the circr-xmferen-tial pattern extending about it.

My invention for illustrative purposes herein, is embodied in two like machines, 4arran edside by side, each quiteindependent o the' other, and cach operable independently of the other, but,.for convenience in construction, I have omitted what would be the adjacent side frames ofthe two machines,and have continued the shafts and some .of Vthe supports4 continuously from one outside frame to the other, this being a mere convenience however and not a necessary construction. Since these machines are similar in all respects, it is necessary to describe but on'e herein, it being understood 'that like letters represent like parts, operatonefor each machine,-and each of these pinions is provided at its inner end (see Fig.

6) with a large friction flange c, which is embraced at lts peri hery by the o posed and relatively movab e fri tion memlibrs a5,

a. of a friction clutch. The Afriction member c5 embraces the periphery of the inion flangeA collar a.9 grooved circumferentially to receive the forked end of the clutch lever al". This clutch lever is mounted upon the horizontal pivot a supported in the frame and is provided with an arm e, joined by a link cl3 to a short arm a on the horizontal actuating s aft (L15, also mounted in theframe. This shaft carries at its opposite side an arm am; and to the upper end of this arm is joined a brake actuating yoke af" (see'Figs. 6l and 7)., the arms of which conver e and embrace the wedge-shaped ends (L18 o Va brake band el suspended from above at the fpoint a2 and encircling the smooth braking portion of the pinion a3.

Obviously, if the horizontal 'actuatingA shaft a.15 be rocked in the direction of the arrow (Fig. 6),. it will cause the sleeve. a. to slide toward the 'middle of the machineiand by s reading thetails of the clutch levers, clutc the splinedl hub c7 to the pinion flange a4 and cause the latter to rotate in unison with it. This same rockin movement of the'said actuating shaft 0.15 lifts the yoke a" and releases the ends of the band brake permitting the latter to spring outward away from and to release the pinion.

Reverse rotation of the actuating shaft.

(1.15 will release 'the clutch and a ply the brake. In lieu of the clutch and braille-mechanism here shown, any other suitable clutch and brake or driving device, or fast` and loose pulleys may be employed. l

The actuating shaft am is extended' to the front of the. machine where (see Fig. 2) it is provided with a'laterall'y extended arm c, connected by a link te? with a treadle @23, fulcrurned at ai andsupported from below by a spring cz.- De ression of this. teadle causes the drive sha t to be clutched o its pinion andthe brake to be released, while release of thev treadle unclutches 'the pinion and a plies 'the brake.

Re erring now to Fig. 1, the driving pinion c3 meshes with and drives the larger toothed .wheel b, fast upon the horizontal shaft b journaled in the frame.V This shaft b also carries the small pinion t that meshes with and drives the .larve eaniwheel b3 loose'upon the horizontal lsha t b'fj ournaled'in the frame.

'This cam wheel has formed in one of its side faces a suitable jack actuating .path-cam',

shown best in Fig. .1, which receives the roller stud 54X on the arm b5 fulcrumed in the frame at band provided with the dependingl arm b?. This depending arm 67 is connected by a link or connecting rod 0' with the lower, slotted end of the .jack actuating arm b9, fulcrumed loosely upon the shaft bw, itself loosely mounted in the frame. By varying the point of connection of the link bs with the slotted end of the jack lever b, the extent of oscillation of the jack lever and its jack may be varied as required,

The jack lever b9 (see Fig. 4) is provided above its shaft b1 with three u wardly inclined and substantially paralle members7 the two outer of which are marked bu in the drawing, and the middle of which is marked 512.

The middle member b1? is provided at its upper end with an obliquely arranged table c upon which rests the base c of the shoe support or jack. rThis jack may be of any suitable or desired construction, but as herein illustrated it comprises a .heel post c2 provided at its upper end with a usual spring controlled and fulcrumed heel supporting pin c3 and an adjustable toe support c4. T-he last, carrying a shoe the sole of which is to be leveled or beat out, is supported in usual manner by and upon this jack.

The jack base c is provided with a downwardly and obliquely extended guide rack c5, shownbest in Fig. 4, arranged to slide in a suitable guide-way provided therefor in the jack supporting'member Z112. The rack face of this guide is in mesh with the toothed wheel c loosely mounted in the said jack supporting member 512, said pinion in turn being engaged by a segmental gear c7, fulcrumed at e8 in an arm of the jack carrying lever b9. This segmental gear has a depending arm c9 carrying at its lower end a roller c1", which, as the jack is oscillated about its fulcrum b1 is caused to rise and fall in the stationary slot cam 011 suitably supported upon the frame. This-slot cam is so shaped, with an offset at its lower end that, as the jack is oscillated to the right, Fig. 1, toward the operator7 just before it reaches the limit of its outward movement, the roller c1 will reach the offset and will cause a quick inward movement of the segmental gear c7,

Athereby through the pinion cG to cause the rack guide c5 to be slid outward and upward carrying with it the jack base, jack and shoe thereon. The effect of this is to project the shoe diagonally upward and forward toward the operator, completely above the rolling or leveling devices to be described and into convenientV position for lremoval of the shoe and the placing of a new shoe thereon. Return 4movement of the jack, causes the same to be returned'to its lowermost position to present the shoe to be operatedipon by the leveling devices.

As stated in the preamble, it has been customary heretofore in machines of this type so far as known to me, to level the shank by. a roller or device that traverses from toe to heel of the shoe or vice versa in a line substantially parallel with the longitudinal median line of the last and it will be understood that by leveling means I mean any tool or device that is adapted to shape the sole of a shoe by its action thereon or in cooperation with the shape or `form of the last.

My invention contemplates shank leveling means that enter upon or leave the sole upon the last from the side thereof whereby I obtain an entirely novel effect in leveling ma chines.

As herein shown, both the outer members b of the jack carrying lever b9,-that is, the two members between which the jack supporting member has been stated to be located,-are .provided respectively with upright and slightly inclined bearings for the shank leveler shafts d. T hesev shafts, of course', swing or oscillate with the jack, since their bearings are virtually a part of the jack carrying lever, and each of said shafts is provided at its upper end (see Fig. 4) with a vhead d fast thereon referably by a pin, d2, which head is provi ed with oppositely eX- tended ears between which are fulcrumedv at da the shank levelers or tools d4. The upper and nearly horizontal arms of these levers, which may be detachable, as shown, are suitably sha ed at their under sides and preferably roun ed, to adapt them to sweep over and upon the shank of the sole to be leveled; while the lowerar'ms thereof lying substan-` tially parallel with the shaft d are drawn together by the pair of springs d5 (see Fig. 10). Obviously, the action of these springs is to press the upper and nearly horizontal leveler arms frictionally u on .the shank of the sole for the proper leve ing thereof.

shank leveler arms are fitted with rollers Z7 that travel upon a cam d? shaped as desired to cause said arms to be drawn apart against the action of the-controlling springs, thereby to lift the active leveler arms out of operative contact with or away from the shank of the sole. The shape of ,this cam may be such as to permit the active leveler arms to l remain in full contact with the shank during the entire sweep thereof over the shank face, i and to be raised only uponleaving the said shank and to facilitate re-approach of the l same to the shank, or, the said cam may be l shaped so as to vary the spring pressure of the leveler arms upon the shank during the l sweep thereofover the shank surface.

l have obtained excellent results by leaving the shank levelers wholly under the influence 'of the springs d" during the entire effective sweep, that is, during the period in which thedevices traverse the shank face,

The lower ends of the spring controlledl using the cam merely` to lift the shank levelers preparatory to and to facilitate their ini- `tial contact with `the shank and their withof the levelers d? drawal. j Y The entire shaft d, shank levelers and all,

' are themselvesspring supported by a spring d8 encircling the shaft, seated at its upper end upon the threaded and adjustable sleeve d9 and acting at its lower end against the collar d1, fast on the `said shaft. Any lifting that cannot conveniently be permitted bythe leveler springs d will lift the entire shaftfwlevelers and all ,Neompressing this spring d8. This prevents any possible damage to the shoe or to the leveling devices. Y

To rotate the shaft d and cause the inward i sweep of the shank levelers, I provide said vsprocket chfain e7 with a driving shaft near its lower end with a worm Wheel e ,(see Fig. 5,) driven at its inner side by a worm e', mounted on the worm shaft e2 to rotate shaft b by the drive` shaft"andconnectedy by the mechanism described to` and for'oscillating the jack, ing ,shaft '519. and, through .the Worm and worm wheeldescribed, rotatesfy the shank leveler shaft d and itslevelers'atthe proper and relativelyfslow speed to cause them slowly'to sweep. over the shank of the shoe i l .shall be caused heretoferefstated to be mounted toslide on' j u` onthe jack. To give these shank levelers s ort and quick vibratingfmovements in additionto th'ef progressive `Ino ven1 ents, lwhich vibrations' `by sald progressive,- movements tire surface of the shank, I cause th'ewcrnieJ its shaft e2," to be given a rapid' sliding orendwise reciprocation.

doing this will be more clearlygundersto'od thispoint to state t tion of the worm causes a rapi j rocation of the fworm 'wheel and 4therefore a 5 5y rapidI vibration of the shanklevelers without from ia 4later descri i' j inthe least interfering with the worm and worm -'wheel pi'pgressive rotation of the sa-id' levelersto cause the-1n to traverse the entir' ghalnjll Y j I Referring againto Fig. 1,the sideframes A at the upper and rear of the machine lhave suitable bearings'for the horizqritaleccentric shaft f, provided with the belt pulley f that is preferablyseparatelybeltedto the power -clined arm f3;

than thatvof the main drive shaft a that it is inconvenient to drive it from the said drive shaft direct -or by any speed reduction mechvor.

anism that could be conveniently arranged in a frame of the ously, however, the particular means for driving this shaft may be varied as desired. This eccentric shaft is provided with a broad eccentric f2, of which hasa forwardly and upwardly inthe forward end of which is (see Fig. 3)' the eccentric strap size herein used.' Obviprovided with a roll carrying yoke f4 (see Figs. 1 and 3), between the arms of which-isV journaled the fore-partlevelingroll f5. To support this fore-part roll'and at the .same

time furnish means Afor pressing the same yieldingly upon the fore-part of the sole, the said eccentric varm f3, near and preferably at the base of the yoke f* is provided with a cross shaftf", the extended ends of whichare' loosely mounted in the upper ends ofthe two curved ,supporting links f7. their lower ends are joined to the head fs upon the upper end of the substantially vertical 's ring rod f 9, mounted to rise and fall in suitable bearings in the frame. f Encircling this rod is a strongspring f1, seated atits upper end u'pon one of the frame bearings and at its lower'end acting against a convene iently adjustable nut f 11, shown as providedY These links at with a hand'wheelf12 and threaded upon the A lower end of the spring rod f 9. By adjusting this hand wheel nut fn, the tension of the spring f1" may be varied and thereby the resultant. pressure of the fore-part roll upon the fore-part of the shoe sole. When the shoe is removed the under side of the head f8 seats "upon an` adjustable wheel nut fsx and furnishes a support for the fore-part roll, f so thatthe rapid reciprocations thereof by the `eccentric may be continued uninterru tedly,

evenwhen ,the shoe is removed from t e machine.

l Hertofore in levelersl employing a fore-part 1."ol1,'said roll has been made truly and con centrically circular at all points, although of yvarying diameteror concavity to fit approximately the transverse curvature of the forepartof the sole. 'The bottom transverse curvature offthe.fore-partr of the last, howvever, varies constantlyfrom the toe to fthe s'hank, being usually more pronounced ata point intermediate the toe and shank, ordinarily` presenting a nearly flat face in the immediatevicinity of the toe and a low crown or curvature adjacent the shank. Hence,

(fill-of 'fixed curvature or concavity can at est accurately fit the curvature of the sole of 'thefo're-part, such curvature merely approximating the other portions of the last ottom. Attempts to correct this error have led toa quite general custom of canting the :or last bottom at one point only in the length roll carrying yoke so that it may be operated first along one side of the fore-part, then alon Athe other side and finally down the mid le or otherwise, but even then therecan bebut an approXimation`to the transverse curvature of the-last bottom.

My present invention contemplates the-use of a fore-part leveling roll having a varying surface contour extending circumferentially` thereof and Which'for identification may be denominated a pattern surface, as best shown in Fig. 12-so that as it rolls along the fore-part bottom or other portion of the shoe sole to be treated, it fits or gives the curvature vof or to the latter at all points as accurately, it may be, as would a predetermin- -ately molded die such as used in direct pressure leveling machines.

As will be' readily understood from.. the foregoing, and the detailed-view of Fig. 12, a cross section of this roll constitutes a former to shape the sole operated upon and has its surface more or less eccentric relative-to its /aXis, the curvature at the dierentportions of its actin face being the converse of that of the 4last om the toe to the shank or ball line o f the sole and is thereby adapted correspondingly to form or sha'pe the sole with which it is brought in contact as itis simultaneously oscillated or ,progressively moved upon it. as will hereinafter more fully appear. this`roll should be such that it will preferably make one complete revolution .in its traverse from the tip of the toe to the beginning of the 'shank of the sole and .will thus give to the latter, a perfectly accurate and predetermined curvature at all points, notwithstanding said lroll is oscillatedor vibrated rapidly back and forth, during its progression or travel along the sole. I

lf it is not convenient to employ a roll of such diameter, a smaller one may be used with suitable means for causing it to make Abut one complete rotation during the entire fore and aft Vtravel along the foreart and, whilethis would involve a sli o the roll 1 during its travel, such slip Wou d not necessaril be detrimental; on the contrary, it'

wou dbe considered by some to be distinctly advantageous because it would provide a 'v This shaft v'has a laterally extended arm f15 wiping action that approximates the hand operation of long sticking the sole. VTo produce such ositive and fixed rotation of the leveling ro l, or, in other words', to con trol its rotative movement during its fore and aft travel along the sole, l have rovided the same herein with a pinionfl, driven by a segmental gear f fulcrumed upon the cross fshaftf" 'at thebase of the roll carrying yoke.

connected by a rod fw with an armf forming a art of the cam actuated lever b5 which o scillates the jack and which therefore oscillats said segmental gear and its rod. By thus.

For the lbest results the diameter of' positively 'rotating or controlling the rota- Y tion ofthe leveling roll in time with and from the same mechanism that 'oscillates the jack, it is possible to use a molded or pattern' surface roll that will cause a predetermined curvature to ,be given to the sole at any point between the toe and the shank by a pattern leveling action, as will be fully understood. lFrom the construction described with respect totheleveling roll, which, for illustra- 75 tive purposes I have selected as a foreart leveling device, it will be apparent to tiiose skilled in the art that as the said device and work support are relatively moved to lsubject different portions of the sole to the level- 8,0

ing operation, the rotative movement of the leveling roll is so controlled that different portions of its pattern surface may be rought into working relation with the sole corresponding to the transverse and longitudinal shape thereof at any point; and, further, that while in such working relation the portion of the sole being treated may be subjected to attritive action by a pattern sur,-

face corresponding to the sole contourdesired. It will also be noted that as the Work supportand leveling device are relatively moved or progressed to bring all desired parts of the soley into position for leveling, the circumferentially pattern surfaced roll 1s 95 progressively and controllably rotated to successively present the proper pattern surface to the sole throughout its extent, and that as each portion ofthe pattern surface of the roll is thus progressively brought into working position, the sole is Vsubjected to a rubbing or attritive action.`

The same eccentric that imparts this rapid vibration of the ore-part leveling roll is utilized to give the rapid endwise reciprocation to the worm e2, already referred to, by connecting the ecentric arm fby a long rod c with a yoke el loosely surrounding the worm shaft and embracing the fends of the worm thereof. Thus, thefOre-part leveling 1h10 roll and the shank levelers vibrate in unison? producing a smooth and perfectly harmonious action of the rapidly moving parts of the machine. Y

-The operation of leveli U a shoe upon my 115 improved machine is as follows :-Assu1ning the j ack to be in its elevated and forward position, as in Fig. 4 and at the extreme right Fig. l, the o erator jacks a shoe thereon and, placing his oot on the treadle starts the machine. As the cam Wheel 'b3 commences to rotate, the abrupt throw in its. path cam l` 1ments in the machine, leavmgonly the rapid cam cu and, by swinging the segmental gear, causes it to operate through its pinion c and therack c todrop the jacked shoe quickly into operative or the lower position shown in Fig. l. rlhis combined inward and down` *y `ward movement of the jack'takes place so lquickly'that the shoe reaches its operative positionbefore either of the side levelers in its llateral swinging or sweepin movement reaches' a position where it wou d eitherpobstruct or contact with vthe shoe.

' From the initial operative position shown in Fig. l, in the subsequent operation of the machine said jack is gradually and automatically oscillated to "the left or inward, causingthe foreart roll f 5 gradually to progress along the ore-part toward the shank.`

Since the side levelers oscillate forwarld.

and backward with the jack, it is immaterial in which direction they progress so far as the fore-part leveling roll is concerned, for their action lis due to the progressive rotation about the axisof the shaft d rather than to any relative travel or movement between said shaft and the jack.

The jackcontinues its'inward oscillating4 movement until the break the sole at the beginning of the shank, reaches the leveling roll when the cam wheel b3 reverses the movej ment of the cam lever l` and causes the jack thereafter gradually to swing outward and toward ythe operator, the side levelersalways following the jack movement. 'When the foreart leveling roll again reaches the toe of theshoe, thev cam b3 gives to the jack a quick `impuls'eforward tocause "the'roller c1 to enter the abrupt offset portionof its stationary slot calmv c, and project the jack upwardly front ofthe operator, as described, free and clear of the fore-part roll and shank levelers to enable the shoe conveniently to be changed. This f abrupt and.' final movement Vof `the jack that projects the shoe intoits elevated Y position for removal, I also utilize` to stop the cam wheel b3 andv arrestv all progressive movevibratory movements of the leveling device to continuer4 jlaccomplish this by. prolonging the end of thej ack actuating lever 67 and connecting to itsflowerend a rod h thate'x# .tendstoward thefrontof the machine .and is there slotted to-reeeivef a stud 7L on the de-- pendin loekxlever h2 normally drawn by la, spring 3 to the-right intopositi'onI to engage` `and lock lthe? treadle'cgi? -in depressed?posijl is thrown abruptly to the left (Fig. 4l) to cause the jack to be projected into its elevated position, as described, the end of the slot in the rod 7L, which, by the gradual throw of the jack has been brought, up to the stud h', engages the said stud and swings the lock# ing lever h2 to the left into its dotted position (Fig. l) to releasethe treadle (L23 and ermit its spring w25 to lift it to unclutch the riving shaftand stop all but theyibratory mo -vements of the leveling devices. i.

Right and left shoes/ordinarily have the y,line of break between the fore-part and the shank extended diagonally at opposite angles, so that the foreepart. length alon the, outer side Aof the sole is longer and the ls ankA length shorter than at the inner side of the sole, and this difference in length of thelforepart and shank at thel outer, as compared with the `inner side of the sole,A varies constantly with different lasts according Vto the degree of swing or style of theI last. lt is therefore impracticable to have two shank leveler shafts d that stand at opposite sides of the last or shoe always one directly oppoat the inner side of the s hoe alone be made,

adjustable, for bymaking it adjustable, it matters not whethera shoe leveled` on that particular jack be a right or a left shoe; this ,Inner shaft may be set inward or outward as maybe necessary to cause its'shank levelers to meet orA leave `the shank at the proper point, with the shoe ositioned so that the outer shankleveler wil properly act upon the outer side of the shank. The means that I ,have provided for thus adjusting the inner shaft d Vis shown in Fig. 5.' Referring to said ligure, said. shaft d hasits bearings provided with laterally extended flanges thatrest upon supporting arms carried by the jack and that are in tongue and .groove engagement therewith, said Jtongues vand grooves being in the arcs of circles above the axis of` the' shaft d as a center. These supporting arms are slotted as indicated in Fig. 5, to receive suitable clamping devices, asf` the bolts dx, f

wherebythe position ofthe said 'inner shaft d may .be de'termined'andfiXedaszoccasion mayrequire; d"

The rapid vibrations of the side levelers upon the one shaft d due to the endwise reciprocations ofthe worm e', are also vtransmitted by the connectin gears g, g tothe opposite shaft d, thus great ylsimplifying the actuhting mechanism for the shank levelers.

In the majority of instances the peculiar and novel movements given to the side levelers d* will cause l thel same when .of like shape,l to act properly ulpon all portions of their res ective sides of t le' shank, as will be evident om an inspectionof Figs, 8 and 11, where it will be seen that the same tool will iit substantially all pitches of either shank side. If, however,lit be found that when of i like shape theyv will not reach all portions of the shank that they should reach, my invention contemplates the use of differently shaped levelers connected, with the same side shaftd, one of which will be shaped to act properly u on given portions of its side of Athe shank, an the other upon other portions- In fact, as many 'shank' levelers thereof.

v the completion of the leveling operation they l will' stand parallel, or substantially so, with thefore and aft length of the shoe, the shoe `may be readily projected upward from between the two shafts and again downwardly into operative position, without interference with or ,from said Vshank levelers.A In fact; in practice I' prefer that when two shank level-A ers only are employed they be arranged not diametricallyopposite one to the"V other, but

Y at an'angle of more than 180o one relative to.

the other, with the larger angle when they are stopped atthe inner side next the shoe lso as to insure sufficient clearance for the shoe in placing it in and removing it'from oper.- ative position.

Y YVhile I'have herein shown two machines associated together, obviouslythree or more might be associated according to the ability o f the operator to handle the shoes andthe speed at which the machine is operated.- However thismay be, kasiat present arranged, ,each machineis complete in itself and performs itsy 'own cycle of operations without interference from, or modification of, its move- `tween the toe and the heel thereof. K novel movementfenables the leveler to enter A`are wipers.

able to employ in one machine Wipers at the ments by the adjoining machine. When the'shoe is jacked for leveling, the machine positions'the shoe, performs its complete leveling operation and again presents the shoe for removal and stops all automatically and remains at rest until the operator removes the shoe, positions another,l and again starts the m achire.

, It will be obvious from the foregoing description how much betterA adapted the machine illustrating my invention is for vleveling all shapes of shoe soles, in the vicinity `of the sh anks thereof aswell as the for'e parts,

' than the ordinary roller leveler as at present constructed and used. The advantages Aof my inventionfare more /fully realized and availed of in .connection withthe most pronounced and unusual shoe Shanks.. In fact, the well-known Cottage shankwhich pre- "sents a distinct' ridge along its median line,

falling ofi abruptly at either side thereof, and which it is impossible practically to level upon the present commercial roller levelers, are accommodated lby the machine illustrating my invention with perfect ease.A So faras I amaware, I am the first to use one or more levelers having a pro ressive movement, ori sweeping'lnward an outward from and at the sides of the sho'e, contra-distille 4guished'from a levelerv having its progressive movement only foreand Aaft of the shoe be- This and leave the worl'rin such a way as tov meet almost any concelvable cross-sectlonal curvature'or shape at any point in the length thereof and without danger of marring the 1 sharpness of the line of break of the ball of the s ole. Furthermore, the leveling devices may be worked simultaneously. VThis insures the holding of the shoe firmly at the fore-part and heel to prevent its buckling or curling between .its ends, and since thelevelers work substantially equally at both sides the median or longitudinal line of `the shoe, there is vno tendency to twistthe shoe laterali or torsionally or to shift itiirst to one an then to the other side upon the jack as vwith the ordinary roller leveler which 1s so detrimental and serious in thc higher rades of light shoes madeupon pronounce lasts that frequently such shoes must be leveled by hand. Asherein illustrated, I empl'o a fore-part leveling roll and shank levelers t rat It is of decided advantage to be shank and a roll at the fore-part, it having been found that wipers are more effective in some classes of work in thesha'nk than rollers would he, and that a fore-part roller when properly controlled is sufficient for the average work but the invention is not restricted to such arrangements or uses, as will be well understood by those skilled in the art.

The positionofthe axis of the shank leveler shafts d' relative tothe shoe sole may be changed .as desired, either by adjusting the shaft bearings or the jack to give to the sole `a different pitch. The latter method is the of the same from the shoe sole may be cons siderably varied so as toiadapt the action of the toolsto thepeculiarities of the Shanks as jack, shank levelingrneans, and means to they may fromtime to time vary.` So far as-.known to me I am the iirst to rovide a vleveling machine vvherein a leve ing device is caused, either by movement ofthe jac'k or of the levelingdevice, -or both,A to

traverse the sole surface td beleveledin a direction oblique to the length of the sole,-

contra-distinguished from machines `of this type that so far asknown to me invariably cause the roll to traverse or rogress over "the she sole in `the`direction of t e length thereof `and havin merely means permitting `it to to the' i vvarious cross-sectional c ycurvatures in the" sole, but Without at adapt -itse anytime alterin itsl eneral foreandsA aft shoe.
